The traditional solution: Bicycle saddlebags

When I travel by bike, then mostly on forest roads. That is, it is vigorously shaken while driving, as the roads are pretty bumpy. I had as yet concerns that this bracket with all the good workmanship and the various attachments is a sure thing.

The smartphone is then eventually disappeared in the bicycle saddle bags, there was simply kept safest. Even if a lost smartphone finds relatively quickly along forest paths, if one loss immediately noticed: whether it can handle such a crash landing, but then is questionable. Therefore: do not even lose, so in the saddlebags, or equal to leave home and take a cheaper mobile phone (eg Nokia with prepaid card.) Where the loss would not be so painful.

The article itself is hardly objectionable, but it does not provide absolute security.
